Abstract: An Integrated Circuit (IC) includes functional circuitry and attack-protection circuitry (APC). The functional circuitry is to receive a supply voltage from a power-supply input. The APC is coupled to the power-supply input and includes a front-end circuit and an averaging circuit. The front-end circuit is to compare the supply voltage to a plurality of voltage thresholds, and to output a respective plurality of indications that indicate whether the supply voltage violates the respective voltage thresholds. The averaging circuit is to estimate, for a selected subset of the indications, respective duty-cycles at which the indications in the subset exceed the respective voltage thresholds. The APC is to trigger one or more attack detection events in response to the indications and the duty-cycles.

Abstract: A computing device includes a non-volatile memory (NVM) interface and a processor. The NVM interface is configured to communicate with an NVM. The processor is configured to store in the NVM Type-Length-Value (TLV) records, each TLV record including one or more encrypted fields and one or more non-encrypted fields, the non-encrypted fields including at least respective validity indicators of the TLV records, to read the TLV records that include the encrypted fields and the non-encrypted fields from the NVM, and to invalidate selected TLV records by modifying the respective validity indicators of the selected TLV records that are stored in the non-encrypted fields.
